@jacobtomlinson: So, I just realized that I don't have admin privileges on this repo. 😄 So, I can't add an API token on the dask/dask-mpi repo.

I can add you to the PyPI project, too, if you share your PyPI username with me.

@kmpaul I've made you an admin here, that definitely sounds like an oversight. I'm jacobtomlinson on PyPI too :).

[kmpaul]

Awesome! Thank you. I'll look into inviting you to the OtPI project.

@jacobtomlinson: Tried to invite you to the PyPI project, but it says that username (jacobtomlinson) was not found....?

[kmpaul]

I've created the necessary secret for this action to work on the main repo (here), so I'm going to merge to test.

@jacobtomlinson: I found your PyPI username and invited you to the PyPI project. If you don't see the invitation, let me know.

[jacobtomlinson]

Ah yeah I always forget about the .. Thanks @kmpaul.

Looks like this went well!

Yes. The action job name is terrible. 😄 But I fixed that. Should be fine for future uses.
